one of the effective methods to improve the thermal efficiency of solar collectors is using nanofluids as the coolant. the present study experimentally investigated the effect of sio2/water nanofluid with 1% mass fraction on the performance of a symmetric collector, i.e. conical solar collector. the conical solar collector with 1 m2 area and normal to the earth was tested in ahvaz, a city in th...
In this research, a pilot study and analysis of an innovative multi-channel photovoltaic/thermal (MCPV/T) system in a geographic location (35° 44' 35'' N, 50° 57' 25'' E) has been carried out. This system consists of integrating a photovoltaic panel and two PV/T heat-sink converters. The total electrical, exergy and energy efficiencies of the system at air flow rate of 0.005 kg/s and radiation ...
Introduction: The aim of this study was to eva-luate the salivation flow rate objectively using Schirmer test and mouth dryness and other consequences subjectively by distributing questionnaires to patients receiving head and neck radiotherapy. Materials and Methods: In this descriptive study that was carried out at Imam Khomeini hospital, Tehran, Iran, the saliva flow rate of 33 patients r...
